Strong quantum computational advantage using a superconducting quantum processor
Yulin Wu, Wan-Su Bao, Sirui Cao +51
Scaling up to a large number of qubits with high-precision control is essential in the demonstrations of quantum computational advantage to exponentially outpace the classical hard…
Quantum walks on a programmable two-dimensional 62-qubit superconducting processor
Ming Gong, Shiyu Wang, Chen Zha +33
Quantum walks are the quantum mechanical analogue of classical random walks and an extremely powerful tool in quantum simulations, quantum search algorithms, and even for universal…
Hardware-efficient quantum algorithm for the simulation of open-system dynamics and thermalisation
Hong-Yi Su, Ying Li
The quantum open-system simulation is an important category of quantum simulation. By simulating the thermalisation process at the zero temperature, we can solve the ground-state p…
Experimental Test of Generalized Hardy's Paradox
Yi-Han Luo, Hong-Yi Su, He-Liang Huang +7
Since the pillars of quantum theory were established, it was already noted that quantum physics may allow certain correlations defying any local realistic picture of nature, as fir…
Deriving Einstein-Podolsky-Rosen steering inequalities from the few-body Abner Shimony inequalities
Jie Zhou, Hui-Xian Meng, Shu-Han Jiang +4
For the Abner Shimony (AS) inequalities, the simplest unified forms of directions attaining the maximum quantum violation are investigated. Based on these directions, a family of E…
Chained Einstein-Podolsky-Rosen steering inequalities with improved visibility
Hui-Xian Meng, Jie Zhou, Changliang Ren +2
It is known that the linear n-setting steering inequalities introduced in Ref. [Nature Phys. 6, 845 (2010)] are very efficient inequalities in detecting steerability of the Werner…
